After returning from Vietnam, Paul A. Campione Jr., a Purple Heart and Bronze Star recipient, came home to his wife and worked many odd jobs until he got into the plumbing industry.

Ricci Hancock helps manage and run his father’s plumbing, heating and AC full service and repair business.

Smatrix Pulse is the industry’s first multizone wireless control system for both radiant heating as well as forced-air heating and cooling.

In a radiant heating and cooling system, water circulates through PEX pipes in the concrete slab to control the slab's temperature for heating or cooling.

Matt Millard, owner of Performance Mechanical in Edgartown, Massachusetts, loves to experiment with new technologies. Recently, Millard wanted to step up to hydronic radiant heating for his own home addition using an air-to-water heat pump.

Hiller announced a five-year partnership with The University of Alabama’s Athletic Department and Crimson Tide Sports Marketing.

This year, High 5 pLUMBING ranked No. 7 in the small business category.

Initially, Thomas & Galbraith Heating, Cooling & Plumbing was only offering plumbing services to homes as far north as Springboro from their Cincinnati office, but now they are hiring Dayton-based plumbers to serve the entire Miami Valley for water heater service, plumbing repairs, water softeners and water quality service, and more from their Dayton location. Initially, Thomas & Galbraith Heating, Cooling & Plumbing was only offering plumbing services to homes as far north as Springboro from their Cincinnati office, but now they are hiring Dayton-based plumbers to serve the entire Miami Valley for water heater service, plumbing repairs, water softeners and water quality service, and more from their Dayton location. 

The owner asked for a bid to replace her 35-year-old cast iron boiler which was still operating. She had two requirements: Redundancy in the event of a boiler malfunction and lower fuel costs for the building.

"According to the ASHRAE HVAC Applications Handbook, the estimated life of an air-to-air heat pump or a rooftop unit is 15 years while a boiler life expectancy is between 24-35 years, depending on the boiler type. So, you will install two heat pumps or rooftop units for every boiler. Where do you think those old units will end up?" I ask the class.

Wheatland Tube's new black steel pipe coating, Ultra Z-Coat, provides enhanced protection to shield against corrosion and rough handling during transit and installation.

The Laars NeoTherm XTR condensing natural gas boiler or volume water heater is available in several MBH sizes all with Laars Linc.

As building codes and programs such as Energy Star and Passive House require higher degrees of air sealing in new construction, the use of heat recovery ventilation (HRV) is increasing.

Many legacy hydronic heating systems use a fossil fuel boiler to supply fin-tube baseboard heat emitters in some areas of a building and lower-temperature radiant panels in other areas. 

Government planners, taking their queues from politicians and advocacy organizations, have steered the future of energy supply away from fossil fuels and toward renewably-sourced electricity. It’s happening on every level from the feds right down to local city councils.

More and more hydronic heating and cooling systems are being designed around air-to-water and water-to-water (geothermal) heat pumps. When the heating distribution system is extensively zoned, a buffer tank is typically installed between the heat pump and that distribution system.

Last month, we discussed the role of buffer tanks in combination with air-to-water and water-to-water heat pumps that operate as “on/off” devices. The key concept was to turn the heat pump on and off based on changes in the buffer tank temperatures and not based on thermostats calling for heat.

The overall objective was to create a complete HVAC system, rather than just a heating + cooling system. The system would provide space heating, cooling, domestic hot water, and fresh air ventilation.

Last month, we began discussing the HVAC system installed at my church’s newly-constructed parsonage. In this month’s column, we’ll complete the picture.

Find out about piping options for retrofitting an air-to-water heat pump into an existing hydronic system.

There is a growing interest in adding air-to-water heat pumps to existing hydronic heating systems. While I support their use, I do not recommend replacing a perfectly good cast-iron boiler that still has a long service life.

In rural upstate New York, residents harvest trees for firewood using chainsaws and hydraulic splitters. I burn about two face cords annually in my wood stove, enjoying its warmth during winter and relying on it during power outages caused by outdated utility lines.

I attended a conference hosted by the Building Performance Association and presented on air-to-water heat pump systems. Many professionals were interested in heat pumps, especially ductless air-to-air systems. One person mentioned the difficulty of finding qualified installers for air-to-water heat pumps and noted the higher cost compared to ductless air-to-air systems.

Air-to-water heat pumps and water-to-water geothermal heat pumps provide warm water for space heating, domestic water heating, and chilled water for cooling. Switching a hydronic heat pump system from space heating to cooling and vice versa seasonally is relatively simple. The system operating mode is changed at the thermostat or a dedicated system mode switch with heat, off, and cool settings.

In 1986, I installed a 1.5-ton geothermal heat pump in my home using two 500-foot horizontal HDPE earth loops. After digging a trench, I connected the loops to the pump and opted for a 2 HP swimming pool pump to fill and flush the system, as a garden hose couldn't provide the needed flow rate.

The Keltech acquisition will also begin a new partnership between Bradford White and Bradley.

The demand for energy-efficient commercial appliances continues to grow — especially as government initiatives continue to promote the use of energy-efficient solutions.

Water heater manufacturer Rinnai America Corp. has been working for the last three years with a state department of corrections to upgrade the water heating systems in five prison facilities.

As natural gas rates increase and the push for more sustainable energy sources intensifies, heat pump water heaters appear poised for massive growth. States such as California and Massachusetts already have regulations prohibiting or disincentivizing gas water heaters in new construction, and New York City recently enacted similar restrictions for new construction. So, are heat pump water heaters the future of the water heating market? Maybe or maybe not — but some industry experts certainly think so.

The commercial water heating market has options for building owners and facility managers when it comes to selecting equipment for their facilities — tank or tankless, gas models or electric — even heat pump water heaters are seeing growth in this space. So which is the most popular? Well, it all depends on who you ask.
